The first thing you should do is read the instructions below as guidance on what we must do to ensure that we do not lose any of our data or files. These instructions will be of even more use to you if you are not used to flashing unofficial Custom ROMS on Android. In this case, it is important that you read carefully.
If you follow the steps properly, nothing should happen to your device, but it is our job to remind you that We are not responsible for any problem that may arise to your HTC One.
Recommendations prior to any system installation
We should always recommend carrying out a full system backup prior to a firmware installation if we do not want to take unnecessary risks. Moreover, for a better system installation we recommend doing a Wipe of our entire system, or what is the same, factory data reset phone (Settings / Privacy / Factory data reset) to erase all data from the old system. In this way, we can restore our backup to the phone once the new firmware is flashed. The truth is that if you make your backup manually with the applications designed for this purpose, such as Titanium Backup, you will have many more options when choosing what to copy or what to restore for the future. It is important to be ROOT to use these types of apps.
We must highlight other aspects that could help you during the process. One of the most typical problems when connecting an Android to the computer is that the computer does not recognize it correctly. This probably happens because you have not activated the mode USB Debugging, which we will find in: Settings> Development options> USB debugging. Activate it and this problem will disappear.
Another point is to make sure that your phone has more than one 85% battery, because if the process takes time to carry out, you could run out of battery running the risk that your terminal is left for paperweights.
HTC One M7: Installing the Google Edition ROM (Stock Android 4.2.2)
Once the backup and all the previous steps have been made, we can proceed to the installation of the new one ROM Google Edition Android 4.2.2 on our HTC One. If you want to make sure by taking a look at the original post in English, here is the original thread installation.
- 1. We must have an HTC One M7, and not another model.
- 2. We must have installed in the terminal a Custom Recovery (TWRP, CWR)
- 3. Some bugs are reported in the forum XDA, during installation on the HTC One M7att. Check the original thread for more information if this is your model.
After having factory data reset terminal, the first thing is download the ROM filtered by XDA forum member, Bigxie. The ROM is housed in a .ZIP file that we must save in our internal memory, in the absence of microSD. Download the file here and do the same.
Now is the time to load Custom Recovery. For that we must enter the BootLoader of our HTC One: With the HTC One turned on we must press the VOLUME DOWN button, and keep it pressed while also pressing the POWER / ON button. We keep both until we see that the screen turns off, at that moment we only release POWER / ON, still pressing VOLUME DOWN until the moment we enter the BootLoader screen.
Once in the BootLoader, we must use the VOLUME UP / DOWN buttons to move through the menu. We must access the RECOVERY, so we position ourselves there, and to enter we give OK with the POWER / ON button.
Already in RECOVERY, we must choose the option of INSTALL ZIP FROM SDCARD to finally install the ROM contributed by Bigxie. Once we select this option we must go to the path of our internal memory where we have hosted the file
bigxie_m7_GPe_odexed_tbalden.zip. We do OK on it, we confirm that we want to flash from the ZIP, and it will begin the installation process of the Google Edition ROM on our HTC One, which should look as follows once the device is restarted and the system boots:
If so, congratulations and enjoy it! And of course, do not hesitate to share with us your experience with the new system!
